Combustor dilution with vortex generating turbulators

A combustor for a gas turbine, the combustor comprising:

• a combustor liner having a cold surface side and a hot surface side;
• a combustion chamber arranged on the hot surface side of the combustor liner;
• a vortex turbulence generator arranged on the combustor liner, the vortex turbulence generator comprising:
• a turbulence generator flow passage extending through the combustor liner from the cold surface side of the combustor liner to the hot surface side of the combustor liner, the turbulence generator flow passage being defined by a turbulence generator wall about a periphery of the turbulence generator flow passage, the turbulence generator wall extending between the cold surface side and the hot surface side;
• and
• a plurality of vortex generating turbulators disposed on the turbulence generator wall, each of the plurality of vortex generating turbulators including a projection portion extending from a surface of the turbulence generator wall into the turbulence generator flow passage and generating a vortex turbulent flow of an oxidizer passing through the turbulence generator flow passage from the cold surface side of the combustor liner to the hot surface side of the combustor liner,
• wherein the vortex turbulence generator further comprises a main jet, the main jet comprising a jet wall having a main jet flow passage therethrough, the jet wall having a jet wall inner surface that defines the main jet flow passage, and a jet wall outer surface, wherein the main jet extends from the cold surface side of the combustor liner to the hot surface side of the combustor liner,
• wherein the main jet is disposed within the turbulence generator flow passage with a gap between the turbulence generator wall and the jet wall outer surface,
• wherein the vortex turbulence generator further comprises a plurality of ribs extending from the turbulence generator wall to the jet wall and radially from at least one of the cold surface side of the combustor liner or the hot surface side of the combustor liner to support the jet wall, each of the plurality of ribs having a side coplanar with at least one of the cold surface side of the combustor liner or the hot surface side of the combustor liner, and
• wherein at least one of the plurality of vortex generating turbulators is pyramidal shaped and includes a primary flow interface surface having a plurality of triangular shaped surfaces, a base of each of the plurality of triangular shaped surfaces extending across an upstream side of the respective triangular shaped surface with regard to a flow direction of the oxidizer passing through the turbulence generator flow passage, and an apex of each of the plurality of triangular shaped surfaces being downstream of the base with regard to the flow direction.
